Diamond Grading

Individual natural diamonds vary greatly; no two of them are alike.
So, the American Gem Society (AGS)
has created a diamond grading system to assist diamond buyers.
The AGS
used to make a chart of the
grades available on their website, but that chart didn’t print
well. Recently, I was shopping around for a diamond and wanted a
small pocket-sized version of the grading chart; so, I made my own
based upon the one the AGS publishes. For detailed information
on how to use this grading chart, please see the
consumer
information section of the AGS website.
